“…Due to the complex compositions involved, use of expensive elements and sophisticated manufacturing equipment, economic feasibility justifies its applications as a small parts incorporated in larger devices [14]. Wieczerzak et al [15] obtained abrasive wear-resistant rapidly solidified bulk Fe-Cr-Mo-C alloys, where hard carbides precipitated in interdendritic zones of ferrite dendrites. Ibrahim et al [16] described Al-Si-Mg alloys with hardening Mg 2 Si phase, used in aerospace industry.…”

“…%) were synthesized by arc melting (Edmund Bühler Arc Melter AM). This method is suitable for synthesis of most metallic alloys, including glass-forming alloys [21], high entropy [22] and conventional crystalline Fe-based alloys [23]. The elemental Cu (purity of 99.995%), Zr, Al (99.999%), Y (99.9%) and Zr (99.8% or 99.5%) in two forms, rod and crystal bar, were used for alloy synthesis.…”

The effect of oxygen content in zirconium on the structure and mechanical properties of the Cu 46 Zr 42 Al 7 Y 5 alloy, in the form of melt-spun ribbons and suction-cast rods, was investigated. Two types of Zr, rod and crystal bar of different nominal purities and oxygen contents, were used to synthesize the alloy by arc melting. Rapidly solidified ribbons were produced by melt spinning and their amorphous structures were confirmed by X-ray diffractometry (XRD) and differential scanning calorimetry (DSC). Bulk samples in the form of rods were cast using a special water-cooled suction casting unit attached to the arc melting system. XRD and DSC studies proved the amorphous structure of the bulk alloy synthesized from low-oxygen Zr and partial crystallization of the same alloy for high-oxygen Zr. In both bulk samples, uniformly distributed crystalline particles were identified as yttrium oxides. Higher mean compressive strength of amorphous alloy was observed. The hardness of amorphous phase was close to 500 HV1 in both bulk alloys, while the hardness of crystalline dendritic areas, observed in the alloy synthesized from high oxygen Zr, was lower by about 50 HV1.

“…In addition, as the first dendrite always grows parallel to the heat flow direction [5], then resulting from the outline and cooling conditions at the edge, the first dendrite axis at position 1 is nearly 45º inclined upwards. As position 2 is away from the radial edge and the thickness at this position is increased, then the cooling rate is reduced, resulting in the coarsening of the crystals.…”

Abstract-A new cold working die steel was prepared by vacuum arc melting. Its structure characteristics and micro-hardness were measured and investigated. The results indicate that the ingot is mainly composed of dendrites. The grain size increases gradually from the edge to the center along the horizontal direction. Along the longitudinal direction, the structure distributes axial-symmetrically and its evolution characteristics in the upper part differ from that in the lower part. The grain boundary segregates are eutectics composed of ferrite matrix and Cr carbides. Compared with the original Cr12MoV matrix steel, the solidification structure of the composition modified steel is improved, resulting in the lower hardness.
